2. WARNINGS

Check the meter before use to make sure there was no damage during

transit.

Check that the insulation on the test leads is not damaged and/or wires

are not exposed.

If any faults or abnormalities are observed, the meter should not be used

and should be checked out prior to use.

Never exceed the protection limit values indicated in specifications for

each range of measurement.

Always be careful when working voltages above 60V DC or 30V AC rms,

keep fingers behind the probe barrier while measuring.

Make sure the rotary switch is in the correct position before measurement.

Never use the meter in an environment with explosive gas, vapor or dust.

Always keep fingers behind probe barriers when making measurements.

When connecting test leads to a circuit, connect the black test lead first,

then the red lead. Disconnect in the opposite order.

Turn off power and discharge all capacitors first before measuring

resistance, continuity or diodes.

Failure to follow safety guidelines could compromise the safety features

of this meter.

Do not use the meter without the battery cover in place.

Replace the batteries as soon as the low battery symbol “ ” to avoid

false reading that could lead to electric shock and injury.

Remove test leads from all circuits before opening the battery cover.

9. CLEANING

WARNINGS To prevent injury or damage to the meter, do not allow moisture

inside the casing. Before opening the battery cover/case, disconnect test leads from all circuits.

Clean the meter regularly with a damp cloth and a small amount of

detergent; do not use abrasives or solvents. Dirty/wet input jacks can

affect readings.

To clean input jacks:

1. Turn off the meter and remove test leads.

2. Brush off any dirt or contaminants from the input jacks.

3. Use a cotton swab with a cleaner/lubricant (i.e. WD40)

to clean the input jack.

4. Use a new swab on each jack to prevent cross contamination.

11. REPLACING THE FUSES

WARNINGS To prevent injury or damage to the meter,

turn off power to the meter and disconnect test leads from input before opening case.

To replace the fuses:

1. Turn off power to the meter.

2. Remove test leads from input jacks.

Remove the 6 screws on the back case

and remove back case from meter.

4. Replace blown fuse(s) with a new fuse.

5. Replace back cover and secure to meter.

3.

10. REPLACING THE BATTERIES

To replace the batteries:

1. Turn off power to the meter.

2. Remove test leads from input jacks.

3. Loosen the screw on the battery cover and remove cover from meter.

4. Replace used batteries with new batteries.

5. Replace battery cover and secure to meter.

WARNINGS To avoid false reading that could lead to injury or damage to the meter, replace the batteries as soon as the “ ” symbol appears. Turn off the meter and remove the test leads before opening the

battery cover to avoid injury or damage to the meter.
